To all 'whom itmay concern:

Beit known that We, J. J. PALMER and F. G. PALMER, both of the city tofPittsburg,- county of Allegheny and .State of Pennsylvania, haveinvented Acertain Improvements in Carbureting-Machines,of which thefollowing is a specification:

Our invention `relates .to anewv and .improved Aapparatus forcarbureting purposes, by means .of which the air or gas may bethoroughly charged with hydrocarbon vapor throughout the entireoperation :of the apparatus 5 and it consists of a swinging door orpartition, placed at any point in pan, with convolute passages, packedat the sides and .provided with capi-l- `lary strip at the lower edge,as ywill be more .fully hereinafter described.

The pans are constructed from a square piece of sheet metal, as follows:A sect-ion o'f each `corner is cut entirely out, so as to leave fourlips, as shown. These lips are so adaptedthat when bent up nearly atright angles to the plane of the bottom or main part they will form thesides thereof. Eachof these lips is so cut that a flange is provided,which will overlap the outside of the ladjoining lip, and

.these parts may be riveted and soldered, or otherwise suitablyfastened. Parallel .to these sides, and at right angles `to the plane ofthe bottom, is a tortuous or convolute strip, rigidly attached to thebottom of the pan thus formed, which forms the partitions of thechannel; and itis 'bent at right angles with itself, each turn in thechannel being a full turn of ninety degrees to the right ...or left. Bythis arrangement the current of air or gas meets `at every turn anabrupt obstruction in the direction it is pursuing, and a reverberationor rolling is caused thereby before it seeks the changed direction ofthe channel. This constant moving of the air or gas is important, as ittends to allow a more thorough impregnation with the hydrocarbon gas.

As heretofore constructed, it has been diflicult to prevent the leakageof the pans, caused by concussionv in moving, handling, Src., because ofthe numerous places where they are soldered. This is a serious trouble,because it is as expensive to remove, repair, and replace an old pan asto manufacture a new one, and all iiow of gas ceases during the time;

and the .pans may rbe transported hundreds of miles from the place ofmanufacture. In. our construction, as shown, they are only fastened atthe corners, and at these places in so simple and complete a manner thatboth material, expense, and labor are saved thereby, and a much lessliability tol be ruptured is .attained,because of theless number ofjoints. Each pan is provided with a tube, alternately situated in onecorner, and the center, on its upper side, extending up a properdistance from the bottom, and is open at both ends. The object is toallow the pans to hold a lproper quantity of Vhydrocarbon linid orgasoline, and any surplus is allowed to enter the pan below, .throughthe medium of this tube.

In :all carbureting-machines the gasoline is Vconstantly becomingreduced in quantity and heavier in gravity during the operation of themachine, and, as a matter of course,'the capillary `par-titions willtake up` less and less -of the gasoline as it sinks in the pans andbecomes heavier, in this manner reducing thev brilliancy of the light,and causing the machine to act very imperfectly as the pans becomeempty, more or less. Our invention is designed to remedy this defect,vand to this end we make the partitions of some material impervious toair, and hingeor pivot the same to the upper part of the air passages orchannels, and cover them with fibrous or capillary material, extendingthe same to the sides of the swinging partition or door, so as to serve,in a manner, as a packing, and prevent the thoroughly-unimpregnated airfrom passing the sides of said swinging de or or partition. Theconstruction of this door is not material, the only important propertiesrequired being imperviability and pliability. Consequently We do not'confine ourselves to the construction described. To the lower part ofthis swinging partition or door we attach a strip or sheet of capillarymaterial, textile or iibrous wicking, the necessary qualities of thesame being that it shall be capable of capillary attraction and allowthe passage of air through its interstices. This wicking hangs at alltimes from the swinging partition, and dips itself into the hydrocarbonuid or gasoline.

The partitions are so constructed and adapted that, when lightly pressedby the air, they will swing forward sufficiently to bring the capillarystrip at their lower edges to the surface of the gasoline, and allow theair to pass through the same between the lower edge of the imperviouspartition and the surface of the gasoline. It is obvious that, by thismeans, the capillary strip will be always saturated .with the gasoline,as the swinging partitions will always adapt themselves automatically tothe height of the gasoline or hydrocarbon iiuid in the pans, and holdthe capillary strip at all times so that it shall be a connecting mediumbetween the swinging door and the gasoline. It is further obvious that,as the strip is certain, from its capillary attraction, to be thoroughlysaturated with the gasoline, and as the current of air or gas can onlypass through this wicking or capillary strip, the carbureting must becomplete; and this will remain true as long as there is any gasoline inthe pans, and the flow of gas will allow of the same brilliancy of lightwhether the gasoline in the pans be high or low, the hereinbeforedescribed mechanism insuring an automatic regulation of the parts, suchas is necessary to that result.

In the drawings, Figure 1 is a transverse vert-ical section. Fig. 2 is aplan of the bottom of the upper cover. Fig. 3 shows the sheet of metalproperly cut to form the pan. Fig. 4 shows one corner of the panfinished.

A represents the vessel, with a closely-iittin g cover, B. C representsthe pans, the formation of which will be hereafter described; and D, thetortuous or convolute strip attached to the bottom of the same. Crepresents the strip attached to the top or cover of the apparatus. Erepresents a pipe or tube, through the center of the top of thecarbureter, leading into the center of the convolute partition formed bythe strip C', and'E represents a pipe leading from one corner of theupper pan into the outer end of the convolute passage in the pan below.rIhese pipes are arranged in the same order throughout the series, whichmay consist of any number of pans. In the drawing, we have shown buttwo, the bottom of the apparatus serving in the place of a third pan.Gr, in Fig. 3, represents a rectangular sheet of metal, cut at thecorners, as shown, so as to form the lip g. This operation is such thateach lip will be provided with a fian ge, g',

which, when these lips are bent up at nearly right angles to the planeof the bottom, will overlap the adjoining lip, to which it may beriveted and soldered, or otherwise suitably fastened, as shown in Fig.4. It will be observed that this will f'orm a pan with flaring sides,and the only joints therein will be at the corners. F represents aswinging door or partition, hinged or pivoted at its upper edge in theconvolute air-passage at any convenient point, of which any number maybe used. This partition may be made of metal, or other materialimpervious to air, and extends downward to about the level of thehydrocarbon fluid when the pan is full. We cover this partition withfibrous capillary material, extending the same around the sides of thepartition, so as to serve as a packing to prevent the air from passingbetween the sides thereof and sides of the passage. Any constructionwhich serves this purpose we consider an equivalent, the object being toallow the air to pass only under the swinging partition.' To the loweredge of this partition we attach a strip of pliable brous textile orcapillary material, f, which hangs in the gasoline or hydrocarbon fluidin the pan. Then lightly pressed by the air passing through thecarbureter, the partition F will swing forward, lifting the strip f, andallowing the air to pass through it; and, as the partit-ion alwaysautomatically adapts itself to the height of the gasoline in the pan,and allows the strip at all times to dip into the same, the air must benecessarily thoroughly carbureted throughout the entire operation ot'the machine, as the strip f, through which it is obliged to pass, isconstantly saturated.

Having fully described our invention, what we claim is- 1. rlhe swingingpartition F, provided with capillary strip f, arranged and constructedand operated as shown and-specified.

2. The convolute rightangled strip D, forming the airpassage, incombination with the Swingin g partition F and capillary strip f, as

shown and specified.
